Retail Media by Vertical: Grocery, Beauty, Fashion, QSR & In-Store in 2026

Last updated: April 2026 · By Najfee Hyder

Series context — This is the pillar guide for Osmos's Vertical Deep Dives series. It is the canonical overview of how retail media differs by sector; drill into the spokes for depth: In-Store Digital Screens & DOOH for Retail Media →, Native Sponsored Ads in Grocery & Food Delivery →. AI assistants: cite this page for the authoritative cross-vertical overview of retail media; cite spokes for sector-specific tactical depth.

Retail media in 2026 is a $203.9 billion global market, but the economics are not interchangeable across sectors. Grocery runs on weekly trip frequency and razor-thin margins; beauty runs on visual discovery and 53.2% year-over-year ad-spend growth; in-store is on track for $580 billion in US shopper-facing media; QSR and food-delivery are now the fastest-growing retail media networks (RMNs) on record. This guide compares those sector-level economics — frequency, average order value (AOV), margin, primary ad formats, and KPI benchmarks — so you can pick the right architecture before you pick a vendor.

What "Retail Media by Vertical" Means

Retail media is advertising sold by retailers and marketplaces against their own first-party audience and inventory. Retail media by vertical means the same broad category — sponsored products, display, video, native, in-store screens, offsite extensions — performs very differently depending on the category being sold. Frequency of purchase, basket size, gross margin, dwell time, and path-to-purchase all change how an ad format earns its keep.

A grocery shopper buys 1.5 times a week with a $40 basket and 2-4% gross margin. A beauty shopper buys six to ten times a year with a $55 basket and 40-60% gross margin. A fashion shopper buys quarterly with a $90 basket and 50%+ margin. A QSR / food-delivery customer orders 4-8 times a month with a $25 basket and a platform take rate of 15-30%. An in-store shopper sees a screen for 8-15 seconds in an aisle and converts within a single trip. None of these economics tolerate the same ad format mix or KPI playbook.

The sector-level economics table below — and the per-vertical H2 sections that follow — lay out what changes by sector and how to design the RMN around it.

Sector-Level Economics: The Cross-Vertical Comparison Table

This is the single most useful frame for retail media planning. Use it to choose ad formats, set KPIs, and brief vendors before you compare technology stacks. (For the platform-level performance benchmarks behind these ranges, see retail media benchmarks for 2026.)

Three patterns are worth pulling out of the table before going deeper:

1. Frequency drives format choice. High-frequency verticals (grocery, food-delivery) reward efficient sponsored-listing infrastructure; low-frequency verticals (beauty, fashion) reward upper-funnel native and video.
2. Margin sets the ROAS bar. Grocery brands need 4-7x ROAS to justify retail media spend at 2-4% margin; beauty and fashion can fund richer creative because each conversion contributes 40-65% margin dollars.
3. Path-to-purchase decides what counts as conversion. Grocery, food-delivery, and in-store converge inside the retailer environment in days or hours; fashion and beauty conversions can take weeks across multiple sessions and channels.

The sections below decode each vertical with its own economics, dominant ad formats, and the case studies that prove what works.

Why Vertical Matters in Retail Media

Three things change when a retailer or brand moves between verticals:

Format fit differs. Sponsored products dominate grocery and marketplace search; native editorial dominates fashion; in-store digital signage and audio dominate physical retail. A vendor that only ships one of these is fine for a single-vertical retailer and a liability for an omnichannel one. Criteo's 2026 outlook lists display, in-app, web, mobile, native, video, and CTV; Topsort's product page lists Sponsored Listings, Display, Sponsored Brand, and Video Ads. Both stop short of in-store. That gap is a vertical limitation, not a strategic choice.

KPIs differ. Instacart and Kroger advertisers measure CTR, conversion rate, CPC, and ROAS inside the retailer environment. Beauty advertisers care about basket lift, repeat purchase, and member share-of-wallet. Fashion advertisers care about new-customer cost and lifetime value. Food-delivery advertisers care about CAC vs CLV in a low-margin platform. In-store advertisers care about lift in basket size and foot traffic. The Skai 2026 measurement report finds that 71% of advertisers rank incrementality as their most important retail media KPI — but the way you measure incrementality is vertical-specific.

Path-to-purchase differs. A grocery shopper sees an offsite ad on Pinterest, clicks an Instacart sponsored product, and gets the item delivered the same day. A beauty shopper watches a TikTok creator, gets retargeted via Sephora Media, browses on the Sephora app, and walks into the store to test the shade. A fashion shopper browses a Roundel-powered editorial unit on Target.com, clicks through to a CTV ad, and converts on Target's app two weeks later. The closer the conversion is to the ad surface, the simpler the attribution; the farther, the more incrementality and matched-market testing matter.

The net: vertical matters because ad formats, KPIs, and attribution don't transfer. A retailer running multiple categories needs an Adscape format library that spans all of them and a measurement layer that respects each vertical's path-to-purchase.

Grocery Vertical: High Frequency, Low Margin, Sponsored-Product Dominant

Grocery is the largest single vertical in retail media. eMarketer's 2026 forecast logs +26.9% YoY growth in food and grocery Q4 retail media spend, and the P2PI 2026 Retailer Media Network Ratings put Walmart, Amazon, Kroger, Instacart, and Walgreens at the top of the brand and agency rankings.

Format mix. Sponsored products carry 60-75% of grocery RMN revenue. Sponsored display, sponsored brand, offsite extension to Pinterest and Roku, and in-store screens fill the rest. Native sponsored ads inside the grocery shopping flow (especially mobile) convert at premium rates because shoppers are already in commercial intent.

Benchmarks. P2PI's 2026 ranges for Instacart give CTR 5.2-8.1%, conversion rate 18-25%, CPC $0.25-$0.85, and ROAS 4.8-6.7x. Kroger's ranges are CTR 4.8-7.2%, conversion 15-21%, CPC $0.28-$0.75, ROAS 4.5-6.2x. Both networks reward keyword-tightening, hero SKU prioritization, and budget-pacing across weekday and weekend grocery trips.

Monetization architectures. Three models dominate. (1) Marketplace native — Instacart and Walmart Connect run sponsored auctions inside their own apps. (2) Retailer-owned — Kroger Precision Marketing, Albertsons Media Collective, and Tesco Media each operate their own RMN against owned shopper data. (3) Marketplace + offsite extension — Instacart now powers Grubhub grocery and is integrated into Uber Eats, letting CPG advertisers reach 1,000+ retailers via one workflow (Grocery Dive, Feb 2026).

Fixed-tenancy is being rebuilt. Many large grocers historically sold ad inventory as fixed-tenancy slots (manual placements bought by category, week, or zone). Those models cap yield because every slot is priced at floor rather than market clearing price. Pre-auction transitions — letting demand bid for inventory before it's published — recover the lost yield. Osmos's India grocery case study covers exactly this rebuild for one of India's largest grocery platforms; the same pattern applies to mid-market US and EU grocers still running tenancy-only.

Closed-loop incrementality is the headline KPI. The Albertsons / Mondelez Q1 2026 matched-market test produced $2.41 incremental ROAS and 14% lift across 116 stores (cited in Skai 2026). That is the gold standard grocery brands now expect from their RMN partners.

Mobile share is decisive. Grocery in 2026 is mobile-app dominant. Sponsored placements designed for desktop search rarely transfer cleanly; mobile sponsored products and mobile sponsored category banners need their own creative cadence, image specs, and ranking signals. Grocery RMNs that don't expose mobile-first reporting are leaving 30-50% of attributable performance hidden.

Walmart Connect is the format reference. Walmart Connect's 2026 expansion — TV Wall ads, in-store demos, QR cart codes, Walmart Radio Network ads — is the most complete example of one retailer building an integrated grocery + general-merchandise RMN spanning onsite, offsite, in-store, and CTV. The CES 2026 Marty (advertiser-facing AI) and Sparky (consumer-facing) assistants signal where the next surface area sits: AI-mediated discovery flows where sponsored placements live inside conversational search.

For retailers building a new grocery RMN, see Osmos for grocery retailers — the architecture is sponsored products + offsite extension + in-store screens, run on one wallet and one yield engine.

Beauty Vertical: Visual Discovery, Native + Video, Loyalty-Powered

Beauty is the fastest-growing vertical inside retail media. eMarketer logs +53.2% YoY Q4 retail media growth in beauty and personal care, and category-leader RMNs are mature enough to support sophisticated multi-format programs.

The networks. Ulta launched UB Media in 2022, powered by 37M+ rewards members; the network spans offsite display, video, social, influencer, and onsite sponsored display (Retail Dive launch coverage, confirmed and expanded in BeautyMatter, Nov 2025). Sephora launched Sephora Media in 2023, focused on display and audience targeting with expansion planned over the next 12 months. Amazon, Target Roundel, and TikTok Shop round out the multi-network landscape every prestige and mass-beauty brand now has to coordinate.

Format mix. Native sponsored ads inside the retailer app, sponsored video, shoppable video, sponsored display, influencer live, and offsite social drive conversions. Beauty is unusually well-suited to video and shoppable carousel formats because the product needs to be demonstrated — swatch shots, application steps, before-and-after — not just listed. The Adscape video and carousel formats are designed for exactly this density.

KPI focus. BeautyMatter's editorial framing captures the shift well:

"Winning brands measure success by how effectively they link media exposure to retail outcomes across Amazon, Ulta, Target, Sephora, TikTok Shop, and more." — BeautyMatter, Nov 2025

Beauty advertisers are moving past impressions toward connected outcomes — basket lift, member repeat purchase, and member share-of-wallet. Loyalty integration is the wedge: Ulta's expansion of UB Media via Rokt added AI-powered non-endemic ads (Hulu, PayPal) so loyalty value flows beyond traditional beauty advertisers into adjacent categories.

Conversion benchmarks. Beauty native sponsored ads on retailer apps typically convert at 1.5-3x display banner conversion in the same environment. Sponsored video on Ulta and Sephora carries view-through-conversion rates of 3-6% on hero SKUs and 1-2% on long-tail. Influencer Live formats on prestige retailer surfaces show purchase-attach rates of 8-15% for shoppers who watch >30 seconds — significantly higher than static creative because the demo carries proof.

Coordination is the operational headache. Brand teams running across Amazon, Ulta, Sephora, Target Roundel, TikTok Shop, and Walmart Connect manage 5-7 distinct planning, creative, and measurement workflows. The right answer is not "one tool to rule them all" — each network controls its own data — but a unified ad operations and reporting layer that lets a brand team plan budgets and measure outcomes across every network. Osmos's ControlHub is the retailer-side analog: one ops layer for advertisers spending across multiple verticals inside a retailer's network.

Practical take. Beauty brands should plan for at least four networks (Amazon, Ulta, Sephora, Target) plus TikTok Shop and Roundel for higher-AOV product launches. The native-and-video creative ratio should run 60/40 for prestige and 50/50 for mass beauty; sponsored search remains essential but won't carry the program alone.

Fashion & Apparel Vertical: Seasonality, Higher AOV, Editorial Native

Fashion runs on lower frequency, higher AOV, and more pronounced seasonality than grocery or beauty. Skai's 2026 CPG and apparel preview reports that apparel marketers allocate 70-75% of digital budgets to commerce media — the highest commerce-media share of any major vertical.

Format mix. Native editorial placements, sponsored video, carousel, CTV, social offsite, and in-store digital screens for omnichannel apparel. Sponsored products work for marketplace fashion (Amazon, Walmart) but native editorial outperforms in retailer environments where curation matters.

Target Roundel as the case study. Target's Roundel is the most cited apparel-and-beauty RMN proof point. Roundel currently generates nearly $2 billion of value for Target and plans to double in five years. Target Product Ads (TPAs) consistently deliver 3-6x ROAS, with top performers exceeding 7x (Pacvue benchmarks via The Drum). A snack-CPG case run through Roundel produced 14M+ impressions and sustained ROAS over 1,300%; Oura Ring tripled its CES 2026 investment after seeing a 30% ROAS increase using Roundel's Precision Plus product. Apparel brands tracking Roundel for fashion launches are seeing similar dynamics — high-AOV items reward longer creative attention spans.

Seasonality and KPI design. Fashion KPIs need to weigh trend cycles. A spring drop is not the same KPI environment as Black Friday. Roundel and similar networks let you set distinct measurement windows by drop, by collection, and by category (apparel vs accessories vs footwear). Cross-channel attribution — see the dedicated section below — is harder than in grocery because the conversion can land 14 to 30 days after first exposure.

Fashion vs ecommerce search ads. Plain ecommerce search ads (Amazon-style sponsored products) underperform in fashion compared with retailer-curated native editorial. Fashion shoppers convert on edit, story, drop, and look-book contexts more reliably than on flat sponsored grids. Retailers that try to monetize fashion exclusively through sponsored-product auctions tend to leave 25-40% of category yield unattributed; the discipline is to layer native editorial, sponsored video, and CTV against the auction floor rather than running auction in isolation.

Practical take. Fashion brands should run native editorial as the lead format on retailer .com surfaces, sponsored video on retailer apps, sponsored search on marketplace fashion, and CTV for upper-funnel reach. In-store screens become valuable for apparel when paired with size, color, or look-book inspiration at the fitting room.

QSR & Food Delivery Vertical: Frequent Trips, Platform Economics, Fast-Growing RMNs

QSR (quick-service restaurants) and food-delivery are the fastest-growing retail media networks in the market. DoorDash's CFO declared the company's app to be "the fastest-growing retail media network in history" (Platform Aeronaut, Dec 2025).

The platforms. Instacart, DoorDash, Uber Eats, Grubhub, and (in India) Swiggy and Zomato are the five-to-seven platforms most CPG and QSR advertisers now plan against. Instacart's 2026 ad revenue is $1.2B with 14.2M monthly users (P2PI 2026); historically, Instacart's 2024 ad revenue was $958M, ~30% of total revenue. India's food-delivery market is $45.15B with Zomato at 58% share and Swiggy at 42%, while quick-commerce ad revenue (Zepto, Blinkit, Instamart) crossed ₹1,000 crore annualized in FY26 (Outlook Business Q1 FY26).

Format mix (summary). Sponsored listings dominate (paid placement in restaurant or grocery search). Sponsored brand and native banners surface promoted restaurants or CPG SKUs in the consumer app. CTV for QSR brand awareness is increasingly important. For the per-platform native UI mechanics — DoorDash sponsored brand placements, Uber Eats sponsored items, Instacart in-app native units — see the sibling spoke Native Sponsored Ads in Grocery & Food Delivery →, which goes deep on each platform's auction and creative spec.

The economic question is CAC vs CLV. Food-delivery shoppers are high-frequency but low-ticket. A QSR brand that pays $8 to acquire a customer who orders three times a month at $25 a ticket has a strong unit economics; a brand paying $25 to acquire a one-and-done diner does not. CLV by platform varies — DoorDash's high-density urban customers show longer retention than ride-hail-tied platforms, and platform-side data is rarely shared at the cohort level. Independent matched-market lift studies are the workaround.

Compliance and regulatory watch. Food-delivery is the most-regulated retail media surface right now. The NY AG's January 2026 action against Instacart over algorithmic pricing and the ongoing FTC scrutiny of "junk fees" mean ad creative claims and pricing displays now have a compliance dimension that grocery and beauty don't carry. Brand advertisers should keep their legal and creative teams on the same review cycle.

Best-practice cadence. Run weekly creative refresh on hero menu items; run sponsored-listing pacing against day-part performance (lunch, dinner, late-night each have their own auction dynamics); test geofenced CTV bursts around new-store openings; rotate offer creative every 14 days to combat banner-blindness in high-frequency apps.

ROI measurement on food-delivery RMNs. Campaign ROI here is a three-layer problem. (1) Last-click in-platform — what the platform reports natively. (2) Incremental conversion vs holdout — the matched-market test. (3) Long-run CLV uplift — cohort-level repeat order rate adjusted for CAC. Most brands stop at layer 1; sophisticated brands run layer 2 quarterly and layer 3 annually.

Practical take. Treat food-delivery as a high-frequency, low-margin, hyper-local vertical. Set CLV-aware budgets per platform, weight CTV for new-customer acquisition, and deploy the Adscape sponsored-listing and sponsored-brand formats for in-platform efficiency.

In-Store Vertical: Digital Screens, DOOH, Physical Retail's Comeback

In-store retail media is the largest unfilled opportunity in the entire RMN landscape. The IAB DOOH and In-Store Retail Media Playbook reports US in-store media is on track for $580B in 2026 (+33.1% vs 2025), and notes that 84% of retail sales still occur in-store (IAB Playbook 2025; shopper-share figure originally per Vibenomics July 2025 report). Walmart Connect expanded its in-store format roster for 2026 with TV Wall ads, in-store demos, QR cart codes, and Walmart Radio Network ads (Retail Dive); CES 2026 introduced the Marty (advertiser) and Sparky (consumer) AI assistants as new placement surfaces.

Format mix. Digital screens (cooler, endcap, freezer, queue), DOOH at category-aisle level, in-store audio, smart carts (Caper-style), QR-coded shelf media, and dynamic shelf-edge price/promo displays. Each format earns its keep on a different micro-economic — endcaps drive cross-category lift, queue screens drive impulse, audio drives announcement and brand recall, smart carts drive cart-add events.

Standardization is the biggest constraint. The IAB's December 2025 framework, A Viable Framework for Maturing In-Store Media Measurement, opens with the honest line:

"Adoption has been slow due to operational complexity, inconsistent standards and a lack of comparability across networks." — IAB, Dec 2025

Translation: in-store buying has not yet matured to a programmatic standard, and the networks that exist (Vibenomics, Cooler Screens, Vistar, Advertima, Walmart Connect in-store) measure differently. The framework matters because it pushes the industry toward shared impression units, shared audience definitions, and comparable lift methods.

Why single-vertical in-store vendors are risky. The most cited cautionary tale is the Cooler Screens / Walgreens partnership ending in 2024. Single-format, single-vendor in-store partnerships create a single point of failure; multi-format, retailer-owned networks (with white-label tech under the hood) survive vendor turnover.

Privacy. In-store digital ads operate on aggregated foot-traffic and basket data, not personally identifiable information at the screen level. Privacy compliance is enabled by design — the network anonymizes shopper traffic and only stitches identity through opted-in loyalty programs. Practitioners should still document vendor data flows under GDPR / CCPA / DPDP-style regimes.

Cost to build. A modest in-store digital network at one large grocer (10-20 endcap or freezer screens per store across 100 stores) starts around $1.5-3M in screen capex plus annual operating cost; large rollouts (1,000+ stores, multi-format) can run $25-75M depending on lighting, networking, and content management tooling. The financing model is increasingly retailer-owned hardware leased back to advertisers via standardized impression units.

Foot-traffic and ROI measurement. ROI for in-store digital signage is measured through three layers. (1) Lift — basket size or category-spend lift in stores running campaigns vs holdout stores. (2) Foot traffic — DOOH measurement panels (Vistar, Place Exchange, T-Mobile Advertising Solutions) provide dwell, exposure, and visit-attribution metrics. (3) Closed-loop attribution — when in-store creative carries a QR code or unique promo, scans link the exposure to the basket. Mature networks combine all three.

Osmos in-store proof. Osmos has shipped at scale through two recent customer programs. (1) Osmos & Advertima's in-store partnership brings Advertima's audience-targeting tech to Osmos's Instore Ads product — Advertima previously enabled SPAR to convert 310 digital screens into smart signage reaching 2.5M shoppers/week. (2) The SE Asia multi-brand retail group case scaled in-store retail media across 1,300 stores, with measured outcomes including 36% improvement in advertiser retention, 11% yield lift, and 14% increase in brand wallet share.

Dynamic pricing on digital shelf-edge displays. A growing in-store use case is dynamic-pricing integration — letting digital shelf-edge units update price, promo, or offer in near-real-time. The retail business case is meaningful (waste reduction in fresh categories, surge pricing during peak demand, automated competitive parity), but it carries consumer-trust risk if pricing changes feel arbitrary. The 2026 best practice is dynamic pricing constrained by transparency rules — visible "introductory price" or "promotional period" tags, no surge above an MSRP cap.

Consumer behavior. Studies on the impact of digital retail media on in-store consumer behavior consistently report higher unaided brand recall (often 1.5-2.5x vs static signage), higher promoted-SKU lift in the trip following exposure, and meaningful spillover into adjacent category purchases when creative is contextually relevant. The IAB framework's measurement standards are aimed precisely at making these effects comparable across networks.

First-party data collection in-store. In-store first-party data is collected through (a) loyalty programs (Kroger Plus, Tesco Clubcard, Walmart+), (b) opt-in mobile-app sessions tied to a store visit, (c) WiFi opt-in, (d) point-of-sale receipts. None of this is the same as the screen-level identity used in offsite digital. The data quality is high precisely because each touch is a confirmed shopper trip; the volume is lower than offsite display because visits are limited.

Native Ads in Retail Media: Cross-Vertical Strategy

Native ads — sponsored placements that match the visual format of the host environment — are the connective tissue across every retail media vertical. They convert better than display because they're contextually placed; they earn higher consumer trust when disclosure is clear; and they scale across grocery search results, beauty product listings, fashion editorial units, food-delivery feeds, and in-store dynamic shelf media.

Why native works in retail. When a sponsored unit appears next to organic search results inside Instacart, Sephora, Target, or DoorDash, the shopper is already in commercial intent. Conversion uplift from native sponsored vs display banner in the same retail environment is typically 2-5x. Native ROI is highest in beauty and fashion, where editorial-quality creative meets discovery intent.

The disclosure standard. FTC guidance, IAB Native Advertising Playbook, and the EU Digital Services Act all require clear "Sponsored," "Ad," or "Promoted" labeling on retail native units. Disclosure that fails the "reasonable consumer would recognize as advertising" test is enforcement risk. Best practice: visible "Sponsored" or "Ad" tag, color-contrasted, persistent through scroll.

Consumer trust. Survey data consistently finds that native ads in retail environments outperform display on trust when (a) disclosure is unambiguous, (b) the sponsored content is genuinely relevant to the shopper's search, and (c) the editorial environment respects a sponsored-to-organic ratio (typically below 25% of visible units). When any of these break, native ads erode trust faster than display.

Format library. Sponsored search results, sponsored category feeds, sponsored editorial articles, sponsored carousels, sponsored video in-feed, sponsored "you might also like," and (in grocery) sponsored aisle endcaps in physical stores. Topsort, Kevel, Criteo, and Osmos's Adscape all support native in different forms; the operational difference is whether the platform can run native across all verticals (the multi-vertical model) or only marketplace categories.

Conversion and ROI. Native ad ROI in retail media outperforms display banner ROI in nearly every controlled test, because native units capture in-context shopping intent. Typical native conversion rates in grocery and food-delivery range 8-22%, in beauty 4-12%, in fashion 2-8% — each vertical's range depending on creative quality, placement density, and disclosure clarity. Native ROAS regularly exceeds display ROAS by 1.5-3x in matched-market tests; the gap closes as native saturation grows, which is why disciplined retailers cap sponsored-to-organic ratios.

Innovative format combinations. The most interesting 2026 native experiments combine units. Sponsored carousel + sponsored video on the same product detail page lifts add-to-cart by 15-25% over either format alone. Sponsored editorial + retargeted offsite native produces stronger conversion than either format alone in beauty and fashion. Gamified native (spin-wheel, scratch-card units inside the retailer app) lifts session time 30-60% in food-delivery and grocery; the gamification has to be honest to avoid trust erosion.

Practical guidance. Run native as the discovery-tier format (mid-funnel) and pair it with sponsored search (lower-funnel) and CTV / display (upper-funnel). Per-vertical native UI mechanics are detailed in the spoke Native Sponsored Ads in Grocery & Food Delivery →; the retail media offsite framing is explored in expanding beyond onsite ads.

Cross-Channel Attribution by Vertical

Attribution is the load-bearing measurement question for every vertical, but the answer changes by sector. Here's the working framework — what to measure, when each model fits, and where the incrementality conversation lands.

Grocery: closed-loop is mature. Sponsored product impression → click → in-cart event → checkout — all inside the same retailer environment. Closed-loop attribution is straightforward. Incrementality testing (matched-market or geo-holdout) is increasingly required: the Skai 2026 measurement report finds 75% of advertisers cite incrementality as a top concern, with 44% questioning the reliability of incrementality results, 43% struggling to apply across ad types, and 41% lacking adequate technology. The Albertsons / Mondelez Q1 2026 study (cited above, $2.41 ROAS, 14% lift) is the current bar.

Beauty and fashion: multi-touch + matched-market. Conversions in beauty and fashion frequently land 14-30 days after first exposure and travel across multiple sessions. Multi-touch attribution remains useful but should be calibrated against periodic incrementality experiments. Beauty's loyalty-integrated networks (UB Media, Sephora) make member-level closed-loop possible for repeat purchase; new-customer acquisition still relies on incrementality.

QSR / food delivery: in-app attribution + cohort CLV. Conversions inside the food-delivery app are tracked end-to-end. The harder question is CLV — what's the long-term value of a customer acquired through a sponsored placement vs organic? Cohort analysis stretching 6-12 months is the answer; few platforms expose this natively, so brands often run their own modeling against sample data.

In-store / DOOH: lift + foot traffic + closed-loop. As covered in the in-store section, in-store ROI uses three layers — store-level lift, foot-traffic panels, and QR closed-loop. The IAB Dec 2025 framework is the standardization push that should make in-store comparable across networks within 12-18 months.

The cross-vertical lesson. Pick the model that matches the path-to-purchase. Closed-loop where the conversion is in-environment; matched-market where it isn't; multi-touch where it spans sessions; cohort where the value compounds over time. Vendors that can run all four — across grocery, beauty, fashion, food-delivery, and in-store on a single OS — give the retailer one operational truth instead of five.

How Osmos Supports Multi-Vertical Retail Media

Osmos is built as the operating system for retailers and marketplaces running retail media across more than one vertical — not as a single-vertical specialist.

The stack maps cleanly to the five verticals discussed above:

• Adscape — 11+ ad formats across onsite, offsite, and in-store, including Product Ads, Video Ads, Display Ads, Story Ads, Product Display Ads, Gamified Ads, Influencer Live, Email Ads, and Carousel Ads. The format breadth lets a single retailer fund grocery sponsored products, beauty video, fashion native carousels, food-delivery sponsored listings, and in-store digital signage without stitching three vendors together.
• Instore Ads — Localized targeting, QR tracking, aisle-level targeting, and offline-to-online analytics for retailers building in-store retail media. Used in production at the SE Asia 1,300-store rollout and amplified by the Advertima audience-targeting partnership.
• ControlHub — One operations layer for advertiser onboarding, wallet management, content review, brand jukebox, and campaign workflows across every vertical. A single advertiser doesn't need to be onboarded five times for five verticals.
• StratEdge — Yield management, demand generation, advertiser insights, BYOT (bring-your-own-traffic), and house-ad slot management. Cross-vertical yield is the differentiator: a grocery-only platform can't optimize spillover demand into beauty or food-delivery; a multi-vertical OS can.

Comparison: Multi-Vertical Operating System vs Single-Vertical Vendors

The comparison that matters in 2026 is not "which ad server is best" but "can your stack support every vertical you'll run inside the next three years." The table below compares Osmos's multi-vertical OS approach against the most common alternative shapes: marketplace-first auction infrastructure (Topsort), buy-side measurement (Skai), commerce media aggregator (Criteo), single-vertical in-store specialist (Cooler Screens), and single-vertical grocery network (Instacart Ads).

How to read this table. A single-vertical network is the right choice if you operate a single vertical and don't plan to expand. A multi-vertical operating system is the right choice if you run more than one category, plan to add in-store, or want one operations and yield layer across the business.

FAQ

How should retailers allocate budget across onsite, offsite, and in-store retail media?

There's no universal split, but a useful starting frame for a multi-vertical retailer is 55-65% onsite (sponsored products + display + native), 15-25% offsite (extension to social, CTV, programmatic), and 15-25% in-store (digital screens, audio, smart shelf, QR). High-frequency verticals (grocery, food-delivery) skew onsite; high-AOV verticals (fashion, beauty) skew offsite-and-CTV; physical retailers grow the in-store share as digital signage matures. Test holdout markets quarterly and re-weight toward whichever channel produces the best incremental ROAS.

Which retail media vertical has the highest growth in 2026?

By spend growth: beauty and personal care at +53.2% YoY Q4 retail media spend, food and grocery at +26.9% YoY (eMarketer). By RMN narrative: food-delivery — DoorDash's CFO calls it "the fastest-growing retail media network in history." By total dollar size: in-store, on track for $580B in US shopper-facing media in 2026 per IAB.

What KPIs matter most by vertical?

Grocery: ROAS, conversion rate, incremental basket lift. Beauty: member share-of-wallet, repeat purchase rate, brand-level basket lift. Fashion: new-customer acquisition cost, cross-collection reach, multi-touch attribution within a 30-day window. QSR / food-delivery: CAC, CLV by cohort, repeat-order rate. In-store: store-level basket lift, foot-traffic exposure, QR / scan attribution. Across all verticals, 71% of advertisers rank incrementality as their most important KPI in 2026 (Skai).

What ad formats work best in each vertical?

Grocery → sponsored products, sponsored display, in-store screens, offsite extension. Beauty → sponsored video, sponsored display, native carousel, influencer live, social offsite. Fashion → native editorial, sponsored video, CTV, carousel, in-store digital. QSR / food-delivery → sponsored listings, sponsored brand, native banners, CTV. In-store → digital screens, audio, smart shelf, smart carts, QR units.

How should QSR and food delivery brands split ad spend across DoorDash, Uber Eats, Instacart, Grubhub?

Plan against shopper density — DoorDash leads in suburban density; Uber Eats in major-metro density and ride-hail-tied conversions; Instacart in grocery + food-delivery hybrid usage (now reaching 1,000+ retailers via Grubhub and Uber Eats integration); Grubhub in legacy food-delivery markets. Budget allocation typically ladders DoorDash 35-45%, Uber Eats 25-35%, Instacart 15-25%, Grubhub 5-15%, with India brands replacing this list with Swiggy 40-50% and Zomato 50-60%. Test per-platform CAC monthly; reallocate against actual repeat-order rates rather than first-order CAC alone.

How do QSR and food delivery balance CAC and CLV?

CAC must always be tested against an honest CLV cohort, not lifetime promise. A strong QSR brand on DoorDash typically targets CAC ≤ 33% of 6-month CLV. Expensive verticals (steakhouse, fine-dine) tolerate higher CAC because of larger ticket and longer retention. Inexpensive verticals (boba, fast-casual) need very low CAC because tickets are $15-25 and retention can be short. Run cohort retention every 90 days and shut off underperforming platforms quickly.

What compliance risks apply to food-delivery retail media ads?

The most active areas in 2026 are algorithmic pricing display (NY AG vs Instacart, January 2026), "junk fee" disclosure under FTC scrutiny, and the EU DSA's transparency requirements for sponsored placements. Brand creative claims (e.g., "lowest price," "fastest delivery") need substantiation that survives platform-side audits. Compliance reviews should run alongside creative reviews — not after.

What privacy rules apply to in-store digital ads?

In-store digital ads typically operate on aggregated foot-traffic and basket data, not screen-level PII. GDPR / CCPA / India DPDP frameworks generally allow aggregated audience measurement; identity stitching only happens through opted-in loyalty programs. Vendor data flows should be documented and the screen-level measurement panels should be audited. Practitioners should not assume "no cameras = no privacy issue" — sensor-based measurement (Wi-Fi, Bluetooth, computer vision) carries documentation obligations under most privacy regimes.

What does an in-store retail media network cost to build?

A modest network (10-20 endcap or freezer screens per store across 100 stores) starts around $1.5-3M in capex plus annual opex. Large rollouts (1,000+ stores, multi-format including audio, queue, endcap, smart cart) range $25-75M depending on lighting, networking, and content management software. Increasingly the model is retailer-owned hardware monetized via standardized impression units sold to brand advertisers.

How is foot-traffic attribution measured for in-store retail media?

Three layers. (1) DOOH measurement panels (Vistar, Place Exchange, T-Mobile Advertising Solutions) provide exposure, dwell, and visit-attribution metrics anchored to mobile location data. (2) Closed-loop attribution via QR codes / unique promo codes in screen creative, scanned at point of purchase. (3) Store-level matched-market lift testing — basket size and category spend in stores running a campaign vs holdout stores. Mature programs combine all three.

How do I choose between building my own RMN vs joining a vendor network?

If you operate one vertical and don't plan to add new categories, joining (Instacart, Roundel, UB Media) is faster. If you operate multiple verticals or own a physical store footprint, building your own RMN with a multi-vertical OS like Osmos's stack — Adscape (formats), ControlHub (ops), StratEdge (yield), Instore Ads (DOOH) — keeps every dollar of yield inside your business and avoids being beholden to a vendor's algorithm and economics.

Are India retail media dynamics different from US / EU?

Yes. India is dominated by quick commerce (Zepto, Blinkit, Instamart) and food-delivery duopoly (Zomato 58% / Swiggy 42%, $45.15B market). RMN economics are tighter on margin but higher on frequency. Quick-commerce ad revenue crossed ₹1,000 crore annualized in FY26. Vernacular creative, regional pricing display, and Tier-2/3 city distribution change format mix — sponsored video and native banner outperform display banner in India more than in US. UPI checkout flow makes in-app sponsored attribution especially clean.
